This compile-time method is obsolete now that we have the logging while
disarmed feature

Uncommenting this line in APM_Config.h will start logging as soon as the
board starts up instead of waiting for the vehicle to be armed

this allows selection of protocol type on telem2. The default is
MAVLink, but can be selected as FrSky protocol

This saves 2k of flash which allows the code to fix on the APM1/2

This saves 1k of flash and we are desperately low on the APM1/APM2.
Hopefully we can find savings somewhere and re-enable it by default.

We have run out of flash on the APM2, it was a choice between Hybrid
flight mode and OF_Loiter

Hybrid flight mode costs 4.5k of flash which currently puts us over the
limit for APM1 and APM2 unless optical flow or other features are
disabled

This is unfortunate but master's flash size is over the APM2 limit

Motors should be attached to RCOutputs 1 and 2, Flaps should be connected
to RC outputs 3 and 4

default behaviour remains as before, this is an compile time option only

this is the newest singlecopter airframe programme.
This kind of aerial vehicles include Honeywell T-hawk and Goldeneye.

Only define and call functions if the appropriate #define in
APM_Config.h has been added

Remove items that can be more easily set with parameters
